Welcome, don't know which part of Spain you are from, however, don't worry about your command of English.
Matter of fact, don't worry about your "Spainish" as most here are not used to real Spanish, I believe the correct term is Castillion (can't spell it correctly, so we will get along fine), most here are more used to Puerto Rican, Cuban or Mexican, just a "tic" off of real Spanish.
In years past, before I retired, spent some wonderful time in Barcelona and Valencia, would go back there is a minute, sorry, but never been to the south or interior of Spain.
